V3-P stand for the Value up Innovation for product process program in NISSAN, which is aimed for the most efficient vehicle development , shortening of development term and to spend the more time for engineer's creative job. We have the three main scheme, "Know how CAD", "Digital test (CAE)" and "Digital prototype" to achieve V3-P. Know how CAD is the system which achieve storage and reuse the manufacturing know how include standard process and structure. Inexperienced engineer can receive standard process and structure same as skillful engineer from it. Know how CAD is utilized not also in Japan but also in whole the world and makes most efficient and high quality for vehicle development in V-3P.
